POSITION OVERVIEW

A rapidly expanding, entrepreneurial technology company, , is seeking an ambitious and talented RF/EMC Engineer. Very few small companies innovate and develop across such a broad range of technologies as

The RF/EMC Engineer position is ideal for candidates who want to work hands-on with technologies such as cellular networks (LTE, Cat-M, NB-IoT, Red Cap, eRedCap), WiFi, Bluetooth, LoRa and mesh/star sub-GHz networks. Opportunities include testing, validating, and certifying the performance of cutting-edge security devices, innovative sensing applications, and life-safety devices. This is a lab-focused role for an engineer who enjoys owning test execution end-to-end — from bench measurement through external certification — while contributing to the RF and EMC quality of in-house hardware designs.

RESPONSIBILITIES
  • Independently plan and perform RF performance and EMC pre-compliance testing in accordance with product specifications and applicable regulatory requirements (FCC, ISED, CE/RED).
  • Complete RF performance measurements (e.g., TRP/TIS, conducted power/spectrum, radiated/conducted emissions) to guarantee high performance across radios.
  • Evaluate, troubleshoot, and help optimize the RF performance and EMC compliance of multi-radio, in-house designed hardware.
  • Own the certification workflow: prepare test samples, develop test instructions, and witness/support testing at external certification labs.
  • Clearly document and analyze test results, and communicate findings to design and program teams.
  • Optimize and expand our testing capabilities using AI tools and other SW tools.
  • Operate independently while working with senior management to stay fully aligned with company priorities, goals, and strategies.
  • Other duties as assigned.
CANDIDATE PROFILE
  • Bachelor of Science degree in Electrical Engineering or a similar technical discipline, with a background in RF and/or EMC.
  • 2-3 years of hands-on experience performing RF performance and/or EMC testing and interpreting results against pass/fail criteria.
  • Familiarity with different wireless communication protocols (cellular, WiFi, Bluetooth, sub-GHz).
  • Experience troubleshooting RF performance issues and EMC compliance failures.
  • Ability to read and understand electronic schematics.
  • Experience using electrical and RF lab equipment, such as: oscilloscope, DC power analyzer, spectrum analyzer, vector network analyzer, signal generator, and cellular communication tester.
  • Rigorous attention to detail with focus on robustness, scalability, and quality of products.
  • Self-motivation and the discipline to thoroughly test and vet wireless devices.
  • Ability to work on multiple projects simultaneously in a fast-paced environment.
BONUS POINTS FOR
  • Familiarity with regulatory certification processes and standards (FCC, ISED, CE/RED) and preparing devices for external certification.
  • Skilled in antenna impedance matching, characterization, and optimization.
  • Experience scripting/automating lab tests using Python or another scripting language.
  • HW engineering design experience including schematic capture, layout design, and hardware bring-up.
  • Experience conducting simulation using Ansys SIwave and HFSS software.
  • Master of Science degree in Electrical Engineering.
